TL;DR: In this paper, the scope of a simple atomic absorption spectrophotometer in the determination of metal ions in solution is illustrated by the results obtained for thirty-six elements and the experimental conditions for each element have yielded lower limits of detection than those reported previously for the atomic absorption method.

TL;DR: A rapid and accurate atomic absorption method for the determination of chromium in faeces samples from pasture experiments using chromic oxide "markers" is described in this article, where the effects of these interferences were overcome by adding calcium to the test solution and by the addition of silicate to the standards, which were prepared in ‘blank’ solutions.
Abstract: A rapid and accurate atomic absorption method for the determination of chromium in faeces samples from pasture experiments using chromic oxide ‘markers’ is described. Of the elements present after ashing and digesting the samples in a phosphoric acid—manganese sulphate—potassium bromate solution silicate, aluminium, calcium and magnesium were found to interfere in the determination. The effects of these interferences were overcome by the addition of calcium to the test solution and by the addition of silicate to the standards, which were prepared in ‘blank’ solutions.The sensitivities of a number of alternate chromium resonance lines relative to that of Cr 3578·7 A. are given. These lines may be used to increase the concentration range of the analysis.The results of a comparison of the atomic absorption method with a chemical method are given.

TL;DR: Experiments on animals provide useful information about the biocompatibility of materials used in the manufacture of total joint prostheses and contribute to bone resorption resulting in prosthetic loosening.
Abstract: The intraarticular effects of alloy wear particles similar in size to those present in the tissues around loose total joint prostheses were studied in rat knee joints injected with laboratory-prepared particulate cobalt-chrome. The particles induced rapid proliferation of macrophages and focal degeneration of synovial tissues similar to the response seen in the articular tissues around loose total joint prostheses in humans. Bacteriologic tests excluded infection as a factor. Wear particles may contribute to the changes in the tissues around total joint prostheses and may contribute to bone resorption resulting in prosthetic loosening. Experiments on animals provide useful information about the biocompatibility of materials used in the manufacture of total joint prostheses.

TL;DR: In this paper, the construction of an atomic absorption spectrophotometer is described and its performance is illustrated by results obtained in applying the instrument to the analysis of solutions, and the results confirm that the sensitivity of the absorption method is independent of the excitation potential of the spectral line used.

TL;DR: The use of organic solvents in atomic absorption spectrophotometry has been investigated in this paper and it has been found that when certain organic solvent types are added to aqueous solutions small increases in analytical sensitivity are obtained.
